DETAILED DESCRIPTION

[0033] The following description is used to disclose the present application so that those skilled in the art can implement the present application.34Obvious modifications.

[0034] As Figures 1-10 An energy-saving direct current motor, comprising a motor shell 1, a rotor assembly 2 is arranged in the motor shell 1, and a rotatable motor shaft 3 is arranged on the rotor assembly 2;

[0035] The rotor assembly 2 comprises a rotor mounted on the motor shaft 3 and a stator mounted in the motor shell 1;

[0036] The rotor is wound with a coil, and the rotor assembly 2 is a commonly used module in the existing direct current motor, which will not be described here;

[0037] An air inlet arc surface 4 and an air outlet mesh surface 5 are arranged on the motor shell 1 respectively;

[0038] The air inlet arc surface 4 and the air outlet mesh surface 5 are both uniformly distributed with mesh holes;

[0039] The sum of the radian values of the central angles corresponding to the air inlet arc surface 4 is 200°;

[0040] A linkage vibration mechanism is arranged in the motor shell 1, and a dust filter frame 6 that can rotate and vibrate synchronously is drivingly connected to the linkage vibration mechanism, the dust filter frame 6 is fixedly connected with an air inlet shaft cylinder 7 that sends air into the motor shell 1, and the air inlet shaft cylinder 7 is sleeved with a tooth cylinder 8 that rotates in the opposite direction coaxially with the air inlet shaft cylinder 7;

[0041] The linkage vibration mechanism comprises a reciprocating frame 15 slidingly connected in the motor shell 1 and an inner frame 16 installed in the motor shell 1, the tail of the motor shaft 3 is provided with a square section 17, the square section 17 is rotatably installed on the inner frame 16, a straight shaft 19 is rotatably installed on the inner frame 16, and the straight shaft 19 and the square section 17 are both provided with first bevel gears, the two first bevel gears are in mesh with each other;

[0042] A cam 20 is installed on the straight shaft 19, a limiting wheel 21 abutting against the cam 20 is installed on the reciprocating frame 15, a reset spring 22 is installed between the dust filtering frame 6 and the motor shell 1, an internal square groove with a tail opening and slidingly connected with the square section 17 is formed in the air inlet shaft cylinder 7, and the square section 17 and the square groove are both regular polygons in cross section;

[0043] Through the linkage vibration mechanism, the dust filtering frame 6 can rotate and vibrate synchronously after the motor shaft 3 outputs the rotating speed;

[0044] When the motor shaft 3 rotates, the square section 17 at the tail thereof rotates, since the square section 17 is rotatably installed on the inner frame 16 and the straight shaft 19 on the inner frame 16 is in mesh with the square section 17 through the first bevel gears, the rotation of the square section 17 drives the rotation of the straight shaft 19. The cam 20 on the straight shaft 19 rotates, and the edge of the cam 20 continuously presses the limiting wheel 21 connected with the reciprocating frame 15 in the rotating process of the cam 20, so that the reciprocating frame 15 moves linearly in the motor shell 1;

[0045] Meanwhile, the air inlet shaft cylinder 7 is slidingly connected with the square section 17 through the internal square groove, when the square section 17 rotates, the air inlet shaft cylinder 7 also rotates, thereby driving the rotation of the dust filtering frame 6, since the reciprocating frame 15 reciprocates, the dust filtering frame 6 vibrates while rotating through the action of the reset spring 22;

[0046] The synchronous rotation and vibration of the dust filtering frame 6 can make the cotton filter belt 11 on the dust filtering frame 6 circularly revolve, continuously change the air inlet angle, reduce the dust adhesion degree of the cotton filter belt 11 by using the centrifugal force, reduce the point contact duration of the dust and the cotton filter belt 11, reduce the adhesion and storage rate of the impurities in the cotton filter belt 11 in the heat dissipation airflow, and improve the dust filtering effect;

[0047] In the running process of the traditional direct current motor, if the dust filtering device is fixed, the dust filtering component is easy to be blocked due to dust accumulation, which affects the ventilation and heat dissipation effect, and the linkage vibration mechanism solves the problems that the dust filtering device is difficult to continuously and efficiently filter dust in the running process and a large amount of dust accumulation leads to the reduction of the dust filtering performance;

[0048] The linkage vibration mechanism further comprises a rotating shaft 23 rotatably connected to the reciprocating frame 15, a rotating bevel gear is mounted on the rotating shaft 23, a bevel gear ring is fixedly mounted on the air inlet shaft cylinder 7 and the tooth cylinder 8, and the two bevel gear rings are in transmission connection with the rotating bevel gear, and the two bevel gear rings are arranged on the two sides of the rotating bevel gear respectively;

[0049] Through the arrangement of the rotating shaft 23, the bevel gear rings and the rotating bevel gear, the air inlet shaft cylinder 7 and the tooth cylinder 8 can be coaxially and reversely rotated;

[0050] The tooth cylinder 8 is respectively provided with a front bevel gear 9 and a rear bevel gear 10, and a rotatable cotton filter belt 11 is mounted in the dust filtering frame 6, and the cotton filter belt 11 is made of cotton material;

[0051] The dust filtering frame 6 is provided with a tension cleaning device for tensioning and cleaning the cotton filter belt 11;

[0052] The tension cleaning device comprises two brush shafts 24 rotatably mounted on the dust filtering frame 6, a rear gear 25 is fixedly mounted on the tail of each brush shaft 24, and the two rear gears 25 are in transmission connection with the rear bevel gear 10;

[0053] Spiral bristles 26 are mounted on the two brush shafts 24 and are in close contact with the cotton filter belt 11, and the two brush shafts 24 are arranged on the outer side of the cotton filter belt 11;

[0054] The spiral bristles 26 are made of wool;

[0055] When the dust filtering frame 6 rotates under the action of the linkage vibration mechanism, the air inlet shaft cylinder 7 is driven to rotate, and the bevel gear ring on the air inlet shaft cylinder 7 rotates accordingly, since the rotating bevel gear on the rotating shaft 23 is in transmission connection with the bevel gear ring on the air inlet shaft cylinder 7, the rotation of the air inlet shaft cylinder 7 drives the rotating shaft 23 to rotate through the rotating bevel gear, at the same time, the rotating bevel gear on the other side is in transmission connection with the bevel gear ring on the tooth cylinder 8, so that the tooth cylinder 8 and the air inlet shaft cylinder 7 are coaxially and reversely rotated;

[0056] The coaxial and reverse rotation of the air inlet shaft cylinder 7 and the tooth cylinder 8 provides a power basis for the realization of a series of subsequent functions;

[0057] For example, the reverse rotation drives the front bevel gear 9 and the rear bevel gear 10 related thereto to rotate, thereby driving the tension cleaning device and the dust shaking device of the cotton filter belt 11 to work, and realizing the cooperative operation of multiple functions;

[0058] Through the above structure, the problem of how to provide reverse rotation power for different components in the rotation system of the same dust filtering frame 6 is solved, and the single motor shaft power source is used to drive multiple components to complete movement in different directions in a limited space, thereby optimizing the structure and power transmission mode of the equipment;

[0059] Four tensioning frames 27 are slidingly installed on the dust filtering frame 6, and a tensioning roller 28 in transmission connection with the cotton filtering belt 11 is rotatably installed on each of the four tensioning frames 27. A tensioning spring 29 is installed on the side surface of each of the four tensioning frames 27 and is limited by the dust filtering frame 6;

[0060] The impurities on the cotton filtering belt 11 are brushed away through the setting of the spiral brush 26. The cotton filtering belt 11 is kept in a tensioning state during operation through the setting of the tensioning frame 27 and the tensioning roller 28.

[0061] Two rotatable dust shaking shafts 12 are rotatably installed in the dust filtering frame 6.

[0062] A front gear 30 in transmission connection with the front gear ring 9 is fixedly installed at the tail end of each of the two dust shaking shafts 12.

[0063] A dust shaking convex roller 13 in abutment with the cotton filtering belt 11 is installed on each of the two dust shaking shafts 12.

[0064] After the output rotation speed of the motor shaft 3, the dust shaking shaft 12 rotates at a set speed. After the rotation of the dust shaking shaft 12, the cotton filtering belt 11 is deformed reciprocatingly through the setting of the dust shaking convex roller 13. The cotton filtering belt 11 is formed in a shaking state through the reciprocating deformation of the cotton filtering belt 11. The dust adhered to the cotton filtering belt 11 is shaken and brushed away after the cotton filtering belt 11 is formed in the shaking state.

[0065] When the gear cylinder 8 rotates, the rear gear ring 10 rotates with it. The rear gear ring 10 is in transmission connection with the rear gear 25 at the tail of each of the two brush shafts 24, drives the brush shaft 24 to rotate, and the spiral brush 26 on the brush shaft 24 also rotates, brushes the surface of the cotton filtering belt 11, and brushes away the impurities on the cotton filtering belt 11.

[0066] During the operation of the cotton filtering belt 11, the tensioning roller 28 on the four tensioning frames 27 is in transmission connection with the cotton filtering belt 11. The tensioning frame 27 always applies an outward pulling force to the cotton filtering belt 11 under the action of the tensioning spring 29, so that the cotton filtering belt 11 is kept in a tensioning state.

[0067] Through the above structure, the spiral brush 26 can more comprehensively and effectively brush off the impurities adhered to the surface of the cotton filtering belt 11, and the self-cleaning ability of the cotton filtering belt 11 is improved. The tensioning frame 27 and the tensioning roller 28 ensure that the cotton filtering belt 11 is always in a tensioning state, so that the cotton filtering belt 11 will not be loose or wrinkled during operation, and the dust filtering effect of the cotton filtering belt 11 is stable. At the same time, it is also beneficial to the uniform brushing operation of the spiral brush 26 on the cotton filtering belt 11.

[0068] Solve the cotton filter belt 11 in the long-term use process due to impurities accumulation caused by filter dust efficiency, and cotton filter belt 11 slack influence filter dust effect and self-cleaning effect problem, prolong the service life of cotton filter belt 11, improve the overall operation stability of the equipment;

[0069] The motor shell 1 is provided with an electric control box 49, and the bottom of the motor shell 1 is communicated with the dust collecting box 18 corresponding to the position directly below the air inlet arc surface 4.

[0070] The dust removed by vibration of the cotton filter belt 11 is collected through the dust collecting box 18.

[0071] When the motor shaft 3 rotates, through a series of transmission structure (such as through the second belt transmission with the bottom shaft 46, the bottom shaft 46 is engaged with the pump shaft 41 through the first gear 47, etc.), the tooth cylinder 8 is driven to rotate, the front gear ring 9 on the tooth cylinder 8 rotates, the front gear ring 9 is in transmission connection with the front gear 30 at the tail end of the dust shaking shaft 12, so that the dust shaking shaft 12 rotates at a set speed, the dust shaking convex roller 13 on the dust shaking shaft 12 rotates with the dust shaking shaft 12, and the dust shaking convex roller 13 continuously extrudes the cotton filter belt 11 in the rotating process, so that the cotton filter belt 11 generates reciprocating deformation, and then forms a shaking state, so as to shake off the dust adhered to the cotton filter belt 11.

[0072] By using the power of the motor shaft 3, the dust shaking shaft 12 is rotated through indirect transmission, and the dust shaking convex roller 13 extrudes and shakes the cotton filter belt 11, so that the dust on the cotton filter belt 11 can be shaken off efficiently, the self-cleaning ability of the cotton filter belt 11 is further enhanced, the working efficiency of the dust filtering device is improved, and a good ventilation and heat dissipation environment during motor operation is ensured.

[0073] The problem that impurities on the cotton filter belt 11 are difficult to be completely removed is solved, especially some tightly adhered impurities, which may not be completely cleaned by simply relying on the spiral brush 26;

[0074] Through the vibration dust shaking mode, these stubborn impurities can be removed, and the good dust filtering performance of the cotton filter belt 11 is maintained.

[0075] When the cotton filter belt 11 shakes under the action of the dust shaking shaft 12 and the dust shaking convex roller 13 and the dust is shaken off, the dust naturally falls into the dust collecting box 18 under the action of gravity because the dust collecting box 18 is arranged directly below the air inlet arc surface 4, and the electric control box 49 is used for controlling the operating parameters of the motor and related components, such as the rotating speed of the motor shaft 3, which indirectly affects the working state of the whole dust filtering and heat dissipation system.

[0076] The setting of the dust collecting box 18 realizes the centralized collection of the shaken-off dust, avoids the dust from flying everywhere in the motor shell 1 to pollute the internal environment of the motor again, and is also convenient for cleaning the dust later.

[0077] The electric control box 49 can accurately control the operation of the motor and related components, ensuring that the entire system operates efficiently and stably.

[0078] The problem of secondary pollution caused by ineffective collection of loose dust is solved, and the precision control of the motor and related components is provided, improving the overall reliability and maintenance convenience of the equipment.

[0079] It also includes four guide rollers 31 rotatably connected to the dust filter frame 6, and the four guide rollers 31 are in driving connection with the cotton filter belt 11.

[0080] When the dust filter frame 6 rotates, the cotton filter belt 11 rotates at a set speed relative to the dust filter frame 6, and after the cotton filter belt 11 rotates, the two spiral brushes 26 can realize the circular cleaning of the surface of the cotton filter belt 11.

[0086] When the large fan cylinder 32 rotates, the air inside the large fan cylinder 32 enters the heat conduction ring channel 33 through the heat dissipation outer slot 35 under the action of centrifugal force;

[0087] At the same time, the first fan blade 36 on the large fan cylinder 32 corresponding to the inner side position of the air outlet mesh surface 5 rotates, and the hot air in the heat conduction ring channel 33 is discharged through the air outlet mesh surface 5, thereby realizing the exhaust of the heat generated by the rotor assembly 2;
